- Knowing what you know about the anatomy of the eyeball, why do you suppose untreated glaucoma (excess aqueous humor production) causes blindness? Group of answer choices a. The excess aqueous humor compresses the optic nerve b. Intraocular pressure increases and the vitreous body presses against the lens c. The fluid accumulation causes the choroid to separate from the sclera d. The buildup of aqueous humor causes the vitreous body to press against the retina and disrupt its blood supply leading to cell death e. Aqueous humor is not reabsorbed as quickly as it is producedarrow_forwardThe posterior chamber of the eye is filled with fluid calleda. tears.b. ciliary body.c. vitreous humor.d. aqueous humor.arrow_forwardwhich statements are true about the Auditory Structures and their Functions a. The middle ear is connected to the mastoid air cells. b. The inner ear has three parts: the semicircular canals; the vestibule, which contains the utricle and the saccule; and the cochlea. c. The cochlea is a circular-shaped canal within the temporal bone. d. The cochlea is divided into two compartments by the vestibular and basilar membranes. The scala vestibuli and scala tympani contain perilymph. The cochlear duct contains endolymph and the spiral organ (organ of Corti).arrow_forward

The external ear consists of the auricle and external acoustic meatus. b. The middle ear connects the external and inner ears. The tympanic membrane is stretched across the external acoustic meatus. c. The malleus, incus, and stapes connect the tympanic membrane to the oval window of the outer ear. d. The auditory tube connects the middle ear to the pharynx and functions to equalize pressure.arrow_forward
- Which two of the following are part of the olfactory organs? a. olfactory receptor cells b. columnar epithelial cells in the nasal mucosa c. the brain d. the eyesarrow_forwardwhat statement is true about Olfactory epithelium and bulb a. Olfactory neurons in the olfactory epithelium are bipolar neurons. Their distal ends are enlarged as olfactory vesicles, which have long cilia. b. The cilia have receptors that respond to dissolved substances. There are approximately 1000 different odorant receptors. c. The receptors activate a G protein complex, which opens ion channels. d. At least 7 (perhaps 50) primary odors exist. The olfactory neurons have a very low threshold and accommodate rapidly.arrow_forwardWhich of the following statements are true of the physiology of vision? (Read carefully and select all the correct statements.) A. Cones are the receptors for color. B. The lens adjusts for distant vision, and the cornea adjusts for near vision. C. The optic nerve is formed by the ganglion neurons of the choroid layer. D. For near vision, the pupils dilate and the eyes converge. E. The optic chiasma is a crossing of optic nerve fibers that contributes to binocular vision. F. The visual areas are in the occipital lobes of the cerebrum. G. The area of the retina for the best color vision is the optic disc. H. Rods are most numerous at the periphery of the retina.arrow_forward
